In my co-pendin application Serial No.

.374,256.01 July 28t 1910 l have described a device for changing the mold in matrixsetting and line-casting machines, which allows to prepare a change of the mold at any moment during the setting of .a line without interfering with the operation of the casting apparatus. With this device it is therefore possible to change the body of the typeand the moldsimultaneously. ln practical use it often happens, however, that the bodyI ot type has to be changed more frequently than the mold within quite a few lines. yWhen for example'matrioes carrying two intaglio-characters of different bodies a re used the mold for the `greater body must be also u"sed..for such lines which only.

contain few letters of theflarger `size, 'the small type mold being only permissible for casting lines containing characters of the smaller body alone. To save the composer all consideration on this point and to get the utmost work out of the line-casting ma` chine, as Well as in order to adapt the latter for Ybeing automatically operated by means .of perforated bands, my present invention provides an improvement of the apparatus described in the before-mentioned appplication.' which automatically sets the mold in conformity with the type used in each line. v In the construction shown in the drawingsvit is supposed that printing matter, containing characters of various body is produced by matrices carrying two kinds of characters of varying heights, which,

kwhen setting lines of matrices', areassemblcdl'in different positions in 'sutl manner' that the character to be cast from a certain matrix always is correctly adjusted into the castin line. A

In tie accompanying drawings Figure 1 shows a front View of the assembling elevator and the device for changing the posi tion of the matrices; Fig. 2 shows a side view of the device shown in Fig. 1 and the mechanism'for operating the same; Fig.3 shows the latter mechanism seen from the rear-side of the line-casting machine; Figs. 4, 5, and 6. show details.

The assembling elevator 1 for assembling the lines of matrices is provided with a lower guide 6, and a longitudinally movable rail 7, forming an upper guide 'for setting the matrices in two varying positions.

the matrices are to be caught in the upper position the rail 7 is ushed forward in known manner toward t e collecting-star 5. In its normal position, in which the Inatrices are collected on the lower uide 6, there is a sullicient space between t e hook 8 and the collecting star-Wheel 5 to .allow the matrices to fall on to the lower guide 6.

The rail 7 is operated by two angle-levers 10, 11 and 12, 13. The lever 1,0, 11 is pivotally mounted on a neck-screw 16 inserted into the body of the assembling elevator 1, and rests with its horizontal arm 11 on the arm 12 of the second angle-lever, the arms.

latter being actuated by the cam-disk 19.

Around the shaft 14 is arranged the torsion-spring 15 which tends to constantly hold the levers 10, 1l, 12, 13 and 18 in such position that the rail 7 is held a distance lfrom the collecting star wheel 5, thus allowing the matrices to drop into the lower position. The-cam-disk 19 and the disk 21 are both mounted on one shaft or spindle4 20. 0n the disk 2 1 is pivoted a forked lever 22 (Fig. 5) which in turn bears a coupling catch' 23. The catch 23 is situated opposite to a crown-wheel 25 which rotates loosely around the shaft 2O and is connected with the pulley 26, by which it is constantly driven. The catch 23 has a lug 27 and is actuated by the spring 28, by means of an intermediate pin 29 passing througha suitable hole in the cam-disk 21. On both sides of the cam-disks 19 and 21 are two levers 30 and 31 (Fig. 2) actuated by a common i spring 32 and pivotally mounted on two neck-screws 33 and 34 on the main frame of the machine. The spring 32 tends to move the lower ends 35 and 36 of the levers 30 and 31 outward. The levers 30 and 31 have beveled faces 38 and 39 situated in the way of the rotating lug 27 of the coupling catch 23 and so arranged that the coupling catch 23. on turning around the shaft 20, engages with one of the saidbeveled faces and is thus withdrawn from the teeth of the crown-wheel 25. Below the ends of the levers 35 and 36 are the armatures 40 and 41 of the electromagnets 42 and Each armature bears a pawl 44 and 45 respectively which. as long as the armature is not I' attracted, hold the two ends of the levers in position against the action of the spring 32. To each of the levers 30 and 31 are further connected the short arms 30ay and V31a respectively, which are actuated by the projections 2la and 2lb of the cam-disk 21 (Figs. 2 and 5), thus bringing the levers 30 and 31 back to their locked position after having been disengaged from the pavls 44 and 45 respectively.

The cam-disk 19 has a recess 19n and a projection 19b (Fig. l). t On its periphery.

may be omitted and any suitable mechanisrn for operating the pawls 44 and 45 may be employed. When one of the electromagnets 42 and 43 is energized 'the respective lever 30 or 31 is released, and the cam-disk begins to move. If, for instance, the magnet 43 is energized the lug 45 will be disengaged from the lever-end 36. The lever 31 consequently rocks outward and retracts the beveled face 39 from the lug 27 of the coupling catch 23. Owing to the action/ of the spring 28 the latter engages in the crownwheel 25 and is rotated with the latter. As a result of the rotation of the cam-disks 19 and 21 which now takes place, the latter rst brings the lever 31 back into the locked position by means of the projection 21 and the lever 31a. During the' further rotation of the cam-disks the roll 60a, which heretoslotted end of the rod 60. The actuation of the lever 18 is transmitted to the anglelever 12, 13 by the draw-rod 17 and by means of the further angle lever 10, 11 to the rail 7 the position of which is then changed. This causes the matrices in the assembling elevator 1 to be placed in their upper' position on the rail 7.

A nger 57 of a lever 55 engages in the upper end of the two-armed lever 58. The lever 55 is pivoted on the leverarm 53 of the two-armed lever 52, 53 by a neck-screw 54 and moves on a right angle -to the movement of the latter. A spring 77 which is attached to the lower arm of the lever 58 tends to hold the levers 58 and 55 in the position corresponding the normal position of the rail 7 in which the matrices are assembled on the lower guide 6 of the assembling elevator 1.

The double lever 49,50 (Figs. 2f and 3) which for the purpose of changing the mold is caused to engage'with the lug 85 on the line-transferring shaft 84, as' described in is pivotally mounted on the pin 51. The

latter is situated in the forked end 52 of the two-armed lever 52, 53.

On the lever 55 is provided a lug 566iposite to which are situated two toothed wheels 65 and 66 which are firmly connected one to another by an intermediate disk 67, in such mannerthat' the teeth of one wheel are placed beside the gaps of the other. Both these toothed wheels are rotarily'mounted on a common pivot 68. A spring-pressed pin 69 engages in suitable holes of the wheel 66, and serves to secure the position of the two wheels 65 and- 66 against unintentional rotation. The lever 55 can be moved b v the lever 58 and the rod 60 so that the lug 56 faces either the wheel 66 or the wheel 65. A pawl 71 which is pivotally attached to the lever-arm 49, engages in the gap between the teeth of the wheels 65 and 66. Each to-and-fro movement of the lever 49, 50 causes the pawl 7l to move forward about the width of one tooth of the wheels 65, 66 and to turn these wheels sothat the lug 56`alternately faces a tooth and a gap, if the position of the lever 55 is not changed.

The lever-arm 53 is provided with an ex! tension 53.a upon which engages a' hook 72a at the end of a rod 72, normally holding the lever 58 in the lower position. Every time the assembling elevator lis raised to pass a line into t-he casting apparatus the rod 72 is raised by means of a lever 7 5 pivotally mounted on a pin 75, and connected with the assembling elevator l by the link 76, tuus ieleasing the lever-arm As a rc sult of the greater weight of the lever 49, mounted on the other lever arm 52, the leverarm 53 turns on the pin 52. This movement can on/ly take place, however, when the lug 56 is allowed to enter one of the gaps in the toothed wheels 65 or 66. lf the lug 56 abuts aga-inst a tooth of one of the two wheels the movement of the lever 53, 52 is prevented. In the downward movement of the lever 49, 50 its lower'end engages, in the manner described in the before mentioned application, with a lug 85 on the linetransferring shaft 84 and thus causes the further necessary operations for the change of mold. Before starting, the wheels 65. 66 must be so adjusted by hand that the lug 56 faces a toot-h of the wheel 65 or a gap of the wheel 66. when the mold for casting types of the higher body is in the normal position vfor use. 'hen on the other hand the mold for casting the smaller letters is in that position. the lug 56 should face a tooth ot the wheel 66 or a gap of the wheel 65.

lThe position of the lever depends on the type employed. and that of the wheels 65 and 66 o n the mold used. lf the mold in working position does not correspond to the height of type used within a line. a change of mold -ta'kes place, the lug 56 entering a gap in the double wheel 65. 66, and causing the downward movement of the lever 49. 50, and the'further processes describedl in the before-mentioned application.

dIt must be, considered that the mold for casting the thicker line-body should also be employed in such cases when only a few characters of the higher body occur in aline; therefore when the end of the line contains characters ot' the smaller bod'y only, after completingl such line the position of the lever 55must nevertheless be that required for characters of higher body. For this purpose a. locking device is provided which holds the lever 55 in thel position required for they higher characters until the end of the line, when it has oncebeen set in this position while. composing the line. This locking device consists of the catch 75 which forms one arm of the angle-lever 7S. 79 and is capable of engaging a lug 8O on the lever 58- as soonas the latter lever arrives in the position corresponding to the higher characters. The catch 78 then prevents the return of the lever into the position corresponding to the smaller characters. After introducing a composed line into the casting apparatus` and appropriatelv actuating thermoldfchanging' lever a9, 50, the catch 78 is raised by means of a pin 74.- on the rod 7 2, i thus releasing the lever 58. If the cam-disk 19 is in the position required for composing small characters the levers 58 and 55 return to the corresponding position, whereas the rod and the levers 58 and 55 remain inthe position required for the higher characters when the canrdisk 19 is in the corresponding position.

On beginning a line a change from the higher to the smaller characters may take place before the irst type has been set. It is therefore necessary to prevent the catch 78 from engagingon the lug 8() when the assembling elevator l returns to the lower position and it must first be seen whether a change is to be made from higher to smaller characters before the composing of. the line is started. or not. To this end the return of the catch 76 to its rest or inoperative po- `,sition is made. dependent upon a further locking device. bv connecting the arm 79 ot' the angle-lever 7S. 7S) to the finger 82 by means of a connecting rod 8l.

ln the assembling elevator l there is arranged the .so-called line-resistant 83% which is mounted on a slide S3. AIf the angle-lever 7h is now raised by the rod T2 the linger 82 is pushed forward so far that the slide S5 on its return to its line-beginning position after the passage. of a line ot' matrices to the line-carriage. engages behind the finger 82.` This prevents the catch 78 from engaging the ing 80 and locking the lever 5S in the appropriate position for high characters. in case the position still exists from the preceding line. As soon as the first matrix of the new line arrives in the assembling elevator the slide 83 advances so far that it releases the finger 82 and allows the catch TS to engage the lugr 80. lf the cam-dislc 19 if: in the position den'ianded by the higher characters before commencingthe line, a nd this position is changed before setting the first character` the lever 55 is also shifted to the position demanded by the small characters. But if the cam-disk 19 is changed after the first character ot' the. following line has been set. the catch 78 first engages the lug H() on the lever 5S and the position oi' tht` lever 55 remainsl uninfiuenced bv the change of body. I

As seen from thc foregoing description` the changing of the mold depends upon the relative positions ot' the lever 55 on the one `hand and of the wheels and 66 on the other hand, the position of the lever 55 correspondingl to the body of type. and that ot' the wheels 65 and 66 to the mold in use.

Means of varying kind mav be employed to obtain a change of the bod;7 of typein a matrix-setting device and my present in* vention may be accommodated to such means by any suitable operative connections between theln and the lever 5511s to adjust the position of said lever correspondingly to the body of the characters employed Without departing from the nature of my invention.
